To aZZ whom it may concern Be it known that 1, D VID SPIVAK, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Window- I Shade, of which the following is a full,

\ clear, and exact description.)

Among the principal objects which the present invention has in view are: to pro- Ivide means for ventilating a room provided with a curtain shade, the ventilators being incorporated in the shade; to provide a window shade with ventilating apertures arranged to obstruct light, while giving free access to air; and to provide means whereby window shades constructed as outlined may be rolled asinmthe conventional manner. I

In the drawings, Figure l is a perspective view of a window shade constructed and arranged in accordance withgthe present invention; Fig. 2 is a vertical section taken on. the line 2-2in Fig. lgFig. 3 is a View of a modified form of the invention.

In the embodiment of the invention shown in the drawings, the shadeS is constructed of conventional material, and is operatively secured upon a winding roller 9 of conventional make, and preferably of the socalled Hartshorn type.

Theshade 8 is provided at intervals with.

severed and outwardly-bowed portions 10.

The portions 10 are suitably reinforced to.

maintain the bowed shape shown in the drawings, so that openihgsll at the sides of the portions 10 furnish a free passage for air, entering and leavingthe room which is provided with curtains so constructed. Where deemed necessary the bowed shape imparted to the portions 10 may be secured by parting the material oftthe shade 8 on the lines 12, the severed edges of the ma terial at this point beingoverlapped to contract the length of the curtain and secure the necessary bulge of theportions 10. The

bulged portions 10 are preferably arranged in line across the width of the shade 8, as shown in Fig. 1 of the drawings. I The various lines of the portionsl0 are spaced apart a distance so calculated thatwhen the shade 1s wound on the roller 9, said porw tions 10 Wlll register or overlayone upon the other, thus making it possible to rolla shade when thus constructed. For this purpose, the roller 9 is preferably provided with a series of form blocks 13, which extend in the first of the portions 10 to rest on the roller 9, and thereafter to prevent the crushingof saidportions 10 by the remainder oi? the curtain 8 being WOllIld thereover. a

In Fig. 3 of the drawings, the modified i form provides principally for the employment of a strlp-of netting 14; or open-mesh material, which covers the back of the shade 1 to hold previously-wound pore dividual sections of precedingseries, to per- I mit rolling said shade.

2. A shade, having a plurality of series of alined, spaced-apart, surface-projected sections, the individual sections in succes sive series being arranged to overlie the in-. dividual sections of preceding series, toper mit rolling said shade; and a meshed covera a ing for sections. a b I a I I 3. In combination, a shade having a plurality of spaced-apart projections, saidprothe openings 1 formed by said jections being raised to provide lateral open- I ings; and a roller having a series of form blocks shaped apart and shaped to coincide with said projections and to fit within the same. i a a 4. A shade having a plurality of outwardly-bowed sections forming with the.

body of the shade lateral openings, said name to this specification in the presene bowed sectlons belng arranged 1n horizontal of two subscrlblng wltnesses. 11nes 1n successlve ser1es; and a roller having a series of form blocks to register With DAVID SPIVAK' 5 and fit within saicl'bowed' sections when the Witnesses: I
